Disclosed are an electrolyte for a non-aqueous secondary battery, a non-aqueous secondary battery, and an additive for a non-aqueous electrolyte that can achieve both high overcharge prevention properties and suppression of deterioration of battery performance. In addition, if necessary, the non-aqueous secondary battery that is suitable for a high-potential positive electrode and a high-potential negative electrode and exhibits the above-mentioned good performance, and the non-aqueous secondary battery electrolyte and non-aqueous secondary battery used therefor An additive for a battery and a non-aqueous electrolyte is provided. An electrolyte for a non-aqueous secondary battery comprising at least one specific aromatic compound selected from the following (A) and (B), an electrolyte, and an organic solvent. (A) An aromatic compound having three or more condensed or linked ring structures and an electron-withdrawing group or an electron-withdrawing linking group (B) A fragrance in which tertiary carbon or quaternary carbon is bonded to an aromatic ring Aromatic compounds in which two or more aromatic rings are connected by an electron-withdrawing linking group |
